De kogel is door de kerk: as we already talked about earlier, Opera is going to switch to the WebKit engine, leaving its own Presto rendering engine behind. We didn't yet know if they would the switch only on mobile or on the desktop as well, and they cleared that up too: both mobile and desktop Opera Browsers will switch to the WebKit rendering engine.

Unless they fork it, they can only extend the project in ways that are beneficial to the community in general, and their submissions will have to be approved.

There is a lot of good that comes from participating in a large, free project like WebKit, but it isn't all roses. There is also a lot of uncertainty and loss of control that comes with it.

If you can't see how that works, I'm not really sure how else to convey it. The closest analogy is that it is like renting your house instead of owning it. You can paint the walls (if you get permission), but you can't remodel the kitchen.
